I have a silverline 4" on an 06... i like it, but if i could change anything, id get one thats a little quieter inside for my crew cab 06 dually. Is an afe, magnaflow, etc any quieter inside at cruise?

The dually i have has 4.30 gears, its ALWAYS in the high rpms and towing sucks because on a stock truck at 3000rpms, its got no power compared to my other 06 with the full 4" turbo back exhaust setup.

I bought one from DPP a year ago, cant find them online now but i think it was less than $400 back then, anything similar out now?

Does yours have a cat or muffler? I have the same exhaust and when the muffler was on it, it wasn't loud in the cab at all. I love mine, especially with the straight pipe.

i agree i just put a 4 in turbo back sytem on my 06 with no cat but i am using the silverline muffler and its not loud in the cab at all a little rumble sound at 2000rpms going do the interstate but its nice i like it. the only thing i didnt like about my silverline exhaust was the cheap *** bolts and nuts they sent to bolt the clamps... i stripped one and the clamp wasnt even tight but i have a bolt bin full of grade 8 bolts so i replaced all of em with different bolts and nuts, i expected this though no big deal.

I absolutely love my silverline. I had MBRP, heard(or didn't hear it as much) my buddy's Silverline, and ordered it the next day! Nice little whistle and whoosh at idle cracks a little when your on the throttle and perfect cruising. If you have the muffler on it, it might just be too many revs on the highway...

Any gains for normal use by going from an aftermarket 4" kit to a 5" kit like mbrp offers? is the downpipe any bigger than the 3.5" in the 4" kits or just the muffler and tip and all? 4" should be fine unless your changing out a lot to make big power right?
